.Application filed February 27, 1915. ?Serial No. 10919.

T 0 all whom it ma e cancer@ i i Be t known that I, A- GUsT J. DI-NKLGE,

.a citizen of the United States and resident of East Orange, county of Essex, and State of New J ersey', have invented a-certa in new operates with a maximum ofrefiiciency :and

which in `addition serves to fsecure the 'rail upon the tieor `sleeper. r t

My "mprovement will be fully described `hereinafter and the features of'novelty will :be pointed out in the appendedclaims.

An example of my invention andtits 'application is shown in :the accompanying draWings in which'- Figure lfiis a `planview; Fig. 2 is :acrosssection on the line 2-'-2 ofFig. l-; and-:Fig 3 is a side view ofone of theelements of ;my

i device.

In the drawings 5 represents the rail hav- :ing the usnal rail base restingeither ;directly upon the `sleepers or ties 7 i or `upon the'tie plates 8 located thereon. The means for securing the rail inposition on the ties which at' the same time comprises the device for preventing longitudinal creeping `thereof consists of screw spikes 9`having the customary heads 10 and angularprojections 11 for the accommodation of a wrench or other tool whereby said spikes' are -screwed 'into the tie 7, the tie plate 8 if used being pro:

vided with apertures 8 through which said spikes eXtend. The shani( or stem of each screw spike 9 is provided, at a point preferably just below the head 10 with teeth or serrations 12 adapted in the operative condition of the parts to mesh with similar teeth or serrations 13 formed on a member 14 depending from a wedge plate 15 having a wedging surface 16 as shown in Fig. 3. When the parts of the device are operatively assembled, the said wedge plate has its wedging surface 16 in surface engagement with the upper surface of the rail base 6 and the depending member 14 in contact with the side edge thereof as shown in Fig. 2. The said wedge plate 15 is thus located between the head 10 and the rail base 6 while the depending member 14 is positioned between the said base and'the stem or shank of the spike 9, it being understood that the wedge plate 15 and depending member 14 are integral with and eXtend at approximately rightangles to each other in cross-section.

i. In assembling the parts the wedge plate 15 is inserted between the rail base and the head 10 before the spike 9 has been driven fully home, the small end a of the wedge plate pointing in the direction in which the rail tends to creep and the depending mem- --ber 14 being in engagement with the side edge of said base G *with the teeth 13 near the end a in mesh with the teeth 12 of the spike 9. The latter is then rotated and driven -fully shome, this operation through the medium of the intermeshing teeth 1:2 and 13 moving the plate 15 and members 14 lengthwise of the rail base to approximately the position shown in Fig. 1 or until .the head 10 rests upon the wedge member 15` as illustrated in Fig. 2. In "the illustration the tendency of the rail 5 is to creep in the direction indicated by the arrow in Fig. 1, thesmall enda of the wedge plates located on the righthandside of the rail base when looking in the direction of the arrow, accordingly pointing in 'this direetion.`

` 'Any tendency of the rail to creep, after the devices are in operative position will Carry along all the wedge plates 15 and members 14 located on said right hand side of the rail and will thus force said wedges more firmly beneath the heads 10 of the spikes 9. At the same time the'corresponding movement of the member 14 will,

through themedium ofthe teeth 12 and 13 -rotate the spikes 9 about their aXis in a clockwise direction to screw said spikes farther into the ties 7. A double clamping action is in this manner Secured; that is the wedge members 15 are driven more firmly beneath the heads 10 owing to the action of the surface 16 on the rail base and the heads 10 themselves are forced down into firmer contact with said wedge plates 15 by reason of the rotation of the spikes as above mentioned. The rail base is thus securely and automatically clamped and the creeping tendency of the rail is immediately checked. If the devices are also located at the opposite or left hand edge of the rail base which need be the case only in single track roads in which the trafiic in both directions is over the same rails, the ends a, of the wedge plates at this opposite edge point in the direction opposite to that of the wedge plates located on the right hand side of said rail. These latter wedge plates and conby the arrow in Fig. 1. When the'traflic is in the opposite direction the operation is the 'same as hereinbefore described, the devices at the right hand edge being inactive during this latter operation. It will of course be understood that in double track roads the described devices need only be located'so as to be operated by the creeping tendency of the rail in whatever direction this may be, ordinary screws or other spikes serving to secure the opposite edges of the rail bases to the ties or sleepers. t

i It will be seen that my device provides a simple structure which not only efficiently prevents creeping of the rails either in single or double track roads but also serves to secure the rails to the ties in a maximumly effective manner. In other words 'the vibration which ordinarily tends to loosen the spikes will in the present case serve to tighten the same more efiectively.

The device is simple in Construction and easy of application and may be incorporated in existing roads without disturbng same.`

Various changes in the specific form shown and described may be made within the scope of the claims without departing from the spirit of my invention.

I claim:

1. The combination of a rail having a base, a screw spike adapted to secure said rail in position and means interposed be tween said spike and rail base whereby said spike is rotated and tightened by the creep'- ing action of the rail and said creeping is checked.

2. The 'combination of a rail having a %sas se-ee spike ma a& ta secure said 3. The combnaton of a rail having a base, a'screwspike adapted to secure said rail inposition, a head on said spike, a

wedge located between said head and the rail base and a connection between said screw spike and the wedge whereby the latter is jammedbeneath said head and the spike is rotated to jam said head upon said wedge by the creeping action of the rail and said creeping is checked.

4. The combination of a rail having' a base, a wedge resting upon said base, a member dependingfrom the outer edge of said wedge and engaging the edge of said base, a screw spike adapted to secure said rail in position, a head on said spike adapted to bear on said wedge and coperating teeth on said depending wedge'member and said spike whereby the'wedge is jamned be"- neath said head andthe spike is 'rotated to jam said head against said wedge by the creeping action of the rail and said creeping is checked. y 4 u e 5. An anti-creeping device for railroad rails comprising a wedge provided with teeth and a screw. spike provided with teeth arranged to mesh with the teeth of said wedge, said wedge and spike being operated one by the other to check a creeping movement of the rail;

In testimony whereofI have hereunto set my hand in the presence of two subscrbng witnesses.
